Poly Lock Valve images

Valve bags are equipped with a designated opening at the upper corner, enabling them to be filled with materials using methods such as air pressure, an impeller, or an auger. Once the contents are inside, the internal pressure created by the product automatically closes the valve, keeping the material safely secured.

One of the standout options among valve types is the Poly Lock. This valve design incorporates a reinforced polyethylene piece that is fitted into the valve opening. The Poly Lock enhances the sealing capabilities of the bag, making it especially suitable for heavier or bulkier materials that require extra strength during handling and storage. Its polyethylene reinforcement adds durability to the bag, preventing leaks and ensuring the product remains intact throughout transportation. The Poly Lock provides a reliable and consistent seal, making it a preferred choice for industrial applications where maintaining product integrity is critical.
